+# --description--
+
+Now let's start fresh and talk about CSS inheritance.
+
+Every HTML page has a `body` element.
+
+# --instructions--
+
+We can prove that the `body` element exists here by giving it a `background-color` of black.
+
+We can do this by adding the following to our `style` element:
+
+```css
+body {
+  background-color: black;
+}
+```
+
+# --hints--
+
+Your `body` element should have the `background-color` of black.
+
+```js
+assert($('body').css('background-color') === 'rgb(0, 0, 0)');
+```
+
+Your CSS rule should be properly formatted with both opening and closing curly brackets.
+
+```js
+assert(
+  code.match(/<style>\s*body\s*\{\s*background.*\s*:\s*.*;\s*\}\s*<\/style>/i)
+);
+```
+
+Your CSS rule should end with a semi-colon.
+
+```js
+assert(
+  code.match(/<style>\s*body\s*\{\s*background.*\s*:\s*.*;\s*\}\s*<\/style>/i)
+);
+```
+
+# --seed--
+
+## --seed-contents--
+
+```html
+<style>
+
+</style>
+```
+
+# --solutions--
+
+```html
+<style>
+body {
+  background-color: black;
+}
+</style>
+```
